Stainless Steel Header Bolts for LS Engine Swaps
When installing an LS engine you require fasteners that endure high exhaust heat and constant vibration. The Stainless Steel Header Bolts deliver a set of 12 stainless steel units each with a 13 mm head and integrated flange, engineered to fit split flange headers precisely. A twelve point head allows fine torque control while the flange underside spreads clamp force evenly across port faces. Precision engineered machining yields smooth threading into LS header flanges without galling, and USA manufacture ensures consistent quality.
300 Series Stainless Steel for Unmatched Durability
Crafted from grade 300 stainless steel, these header bolts deliver exceptional resistance to thermal stress and oxidation encountered in extreme exhaust environments. Their corrosion-resistant nature withstands road salt and moisture, preserving finish and function. This high-performance design maintains consistent clamping force through repeated heat cycles, preventing loosening or warping. Manufactured in the USA under strict controls, each bolt meets precise composition and hardness specifications, ensuring long service life in demanding LS engine applications.
Precision Head Geometry and Flange Seating
The twelve point bolt head design permits accurate torque application with reduced slippage on standard sockets or wrenches, delivering consistent clamp load at critical seal surfaces. A generous 13mm head diameter and integrated flange create a broad contact area that evenly distributes pressure across the header flange, minimizing warp and exhaust leaks. Optimized for headers featuring split flanges, these bolts guide the mating surfaces into true alignment, simplifying installation and ensuring a reliable seal without the need for shims or additional hardware.
LS Engine Fitment and MuscleRods System Integration
Engineered specifically for LS engine header applications, these bolts match the contour and spacing of the factory flange pattern and aftermarket manifold surfaces. When used with MuscleRods mounts, they preserve correct engine placement and maintain optimal drivetrain angles, which is essential for balanced power delivery and reduced component wear. Vibration resistant fastening results from rigorous machining tolerances and thread consistency, ensuring bolts remain secure under high rpm and torque loads. Backed by American craftsmanship, these bolts represent a professional grade solution for performance and reliability in LS engine builds.
Trust these 300 series stainless steel header bolts for secure fastening in your LS swap project, backed by precision machining and USA manufacturing.
